DUST ELIMINATOR FOR HOT-AIR FURNACES.

Application filed August 25, 1926. Serial No. 131,519.

The invention relates to the elimination of dust in hot air furnaces andthe objects of the invention are; first, to prevent dust, smoke, sootand any other particles or fine bits of earth passing from the furnaceto the room through the registers; second, it prevents any sweepings orparticles of dirt, or dust falling into the registers and lodging in thehot air pipes, many times causing fires from these settlings; third, itacts as a labor saving device.

In the drawing, 'for the purpose of illustration I have disclosed apreferred embodiment of my invention,

Figure 1 is a top plan view,

Figure 2 is a view in side elevation,

Figures 3 and 4 are details of a wire mesh attaching ring,

Figures 5 and 6 are details of the sections of wire mesh and Figures 7and 8 are details of the wire mesh spacing clamp.

Referring to the drawings in detail, the invention comprises a pair ofring members 1, each forming a frame for attaching the edges of asection of wire mesh shown at 2, the ends of the wire of the mesh beingbent about the respective rings, substantially in the manner ofclinching whereby to securely attach the mesh and ring to each other.The rings with the Wire mesh attached thereto are disposed in spacedrelation by means of a plurality of spacing flanges arranged at spacedintervals about the edges of the rings, said clamping member beingcomposed of relatively short wire sections having their opposite endsbent about the respective ring members 1.

Between the spaced sections of the wire mesh is arranged a quantit ofsteel wool 4:, loosely acked between sai sections of wire mesh, t e woolbeing prevented from displacement at the sides thereof by reason of thespacing clamp 3. When assembled in the manner as indicated above, and asclearly indicated in the drawings, the device may be spaced transverselyin the hot air pipe of a furnace leading to a floor register or thelike, whereby it will be apparent that the steel wool will act as afilter for preventing dust, smoke, soot or other particles of materialfrom passing into the room from the furnace and also to preventsweepings from the floor of the room from falling into the furnacethrough the floor register. In practice the device is intended to bemade of a size substantially equal to the size of a pipe within whichthe same is fitted Whereby to provide a snug fit between the edges ofthe device and the wall of the pipe so as to frictionally retain thesame in a fixedposition therein.

The device may be periodically cleaned merely by removing the same fromthe-pipe and placing it under running Water so as to wash all looseparticles of dust and other material collected by the wool therefrom.

The dust eliminator can be "used in all sizes and styles of hot airfurnaces, and while the accompanying illustrations show the device in aposition in a floor register, it is entirely feasible to place itelsewhere, as for instance in the wall registers, and can be producedfor any position in the pipes of homes, schools, churches or anybuildings heated with hot air.

I claim A dust collector for the hot air pipe of a furnace comprising apair of wire ring members, each having a section of wire mesh securedthereto by bending the wire ends of the mesh about said rings and aplurality of spacing clamps, each composed of a relatively short sectionof Wire having its opposite ends bent about the respective ring members,said spacing clamps being disposed at regularly spaced intervals aboutthe surface of said ring members and cooperating with the wire mesh toretain a quantity of filtering material therebetween and providing meansfor supporting the material transversely of the pipe whereby to preventthe passage of dust and other particles of solid material therethrough.

In witness whereof, I hereunto subscribe my name this 5th day of May, A.D. 1927.

EDWARD A. STEUER.
